Freezing the image

Press FREEZE on the remote control to freeze the image. The word 'FREEZE' will 

appear on the screen.

 

To release the function, press any key on the projector or remote 

control.

If your remote control has the following keys, please note that they cannot be pressed to 

release the function: LASER, #2, #5, PAGE +/PAGE -.

Even if an image is frozen on the screen, the pictures are running on the video or other 

device. If the connected devices have active audio output, you will still hear the audio even 

though the image is frozen on screen.

Hiding the image

In order to draw the audience's full attention to the presenter, you can use ECO BLANK 

on the projector or ECO BLANK on the remote control to hide the screen image. 

When the function is activated with an audio input connected, the audio can still heard.

You can set the blank time in the 

Blank Timer 

menu

 

to let the projector return the image automatically after a period of 

time when there is no action taken on the blank screen. The length of time can be set from 

5 to 30 minutes in 5-minute increments.

If the preset time spans are not suitable for your presentation, select Disable.

 is activated or disabled, you can press most of the keys on the
